Abstract

A method implemented in a mobile station ("MS"). When the MS transmits, it generates radio frequency ("RF") energy. To limit exposure to RF energy, regulatory agencies determined a maximum transmit power for mobile stations. The amount of RF energy considered safe is that generated when the MS is transmitting continuously at the maximum transmit power for a predetermined period. The method first determines whether the maximum transmit power is too low to effect communication between the MS and a base station. If it is, the transmit power is increased and if possible, the data transmit rate of outbound data is reduced to at or below a data rate threshold that reduces the RF energy generated by the mobile station to an amount considered safe. Then, any data having a data transmit rate less than or equal to the data rate threshold is transmitted at the increased transmit power.
